If I start being who I really am; I'd be an asshole

Now that I've decided to take blogging more seriously, most of my upcoming posts will be about personal growth, people, stories and little ideology bits. Although my older posts represent my past and 'premature thinking' I won't delete them as it'll help me to keep myself in check and measure my growth. I've often heard people say 'Just be yourself', they'll say 'Don't pretend', even my News Feed will pop out these teenage posts advising me to stay who I am. What I don't understand is that do they really understand the circumstances and the weight of their consultation, I mean, if I start being who I really am, I'd be an asshole. One cannot simply be 'just himself'. That would make them socially awkward and probably inactive in society. What I mean to say is all of us are bits and pieces of people we aspire and the people we inspire. We all are stories, different stories formed with interactions, interactions of small levels, big levels, intermediate levels. We are what we believe, assuming all the other negative aspects remain constant. We all are born innocent and naive but by the time we grow up, we all start living in a gutter. Love, happiness and faith are all forgotten and we indulge ourselves in the survival of the fittest. I am what I saw, who I met, the stories I shared, the moments I lived, the things I learned, the food I ate, the girl I had crush on last week and that little part of self-centered ideology. Don't be yourself. Form yourself.
